Analysis of the Value of MSCT for Preoperative Clinical Staging Diagnosis and Recurrence Prediction in Oesophageal Cancer Patients Before Radiotherapy
Objective To investigate the value of MSCT for preoperative clinical staging diagnosis and recurrence pre-diction in patients with oesophageal cancer.Methods Retrospectively selected 108 cases of esophageal cancer patients,all of whom underwent MSCT before surgery,and analyzed the diagnostic value of MSCT on T and N staging and the predictive value of recurrence in patients with esophageal cancer,using surgical pathology examination as the gold standard.Results MSCT diag-nosed esophageal cancer T-stage T1 in 7 cases,T2 in 21 cases,T3 in 47 cases,and T4 in 23 cases,and the diagnostic accuracy was 90.7％,which was in good agreement with pathological examination result(Kappa=0.88),and the difference was not statis-tically significant(x2=0.124,P=0.988);The diagnostic accuracy of MSCT was 91.7％,which was in good agreement with pathological examination(Kappa=0.82),and the difference was not statistically significant(x2=0.003,P=0.958);Gender,age,T-stage,chemotherapy and GTV-L were not correlated with recurrence,while among patients with recurrence,N1 stage,GTV-D≥ 3.5 cm,GTV-V≥23.8 cm3 and GTV-V/L ≥ 3.5 cm were higher among patients with recurrence(all P＜0.05);Logistic re-gression analysis showed that GTV-D,GTV-V and N stage were all independent influencing factors for recurrence in patients with esophageal cancer(P＜0.05).Conclusion MSCT has a very high clinical value for preoperative staging and recurrence risk pre-diction of esophageal cancer,and GTV-D,GTV-V and lymph node metastasis were found to be independent risk factors for recur-rence of esophageal cancer,so MSCT can be one of the main examination modalities for preoperative evaluation of esophageal cancer.
